Account settled before the time but debit order still run on my account

Good day

I settled my account with Finchoice on the 23/09 which was only due on the 26/09. My account was paid up and settle by the 26/09 - 27/09. On the 28/09 my account was debited by Finchoice even after my accoutn was settled. I contacted them immediately to advise them thereof. The Friday 29/09 I called in once again as I was about to reverse the amount myself and they advised not to as they will refund it. I received a ref 221167 at 9:23 logging my query, at 10:13 I received an sms stating it was resolved. I proceeded to call in to find out when the payout will take place and I was advised it was processed for payout and due to the fact that it was a weekend it would only be in my account by today 02/10/2017. I contacted Finchoice today and the lady who assisted me was not the most customer service orientated person I have spoken to. The clients query takes precedent. One can hear the attitude in her voice. She however advised me that she can see the request was sent for the refund but nothing was done/processed other than a request for a refund. She then further said she will send this query through again and I received sms at 11:43 logging my query and at 12:10 sms received that it was resolved.?????

NOTHING has been resolved. I have not received my money either. Awful service, very disappointed.
